Q1.

Select the correct statement.

(A)

If the Brewster's angle for the light propagation from air to glass is $\theta$, then the Brewster's angle for the light propagating from glass to air is $(\frac{\pi}{2} - \theta)$.

(B)

The Brewster's angle for the light propagating from the glass to air is $\tan^{-1}(\frac{1}{\mu})$, where $\mu$ is the refractive index of glass.

(C)

If the Brewster's angle for light propagating from air to glass is $\theta$, then the Brewster's angle for the light propagating from glass to air is $(\pi + \theta)$.

(D)

The Brewster's angle for light propagating from glass to air is $\tan(\mu)$, where $\mu$ is the refractive index of glass.
